Maybe they can tie this into the voting system. That way, if the computer recognizes you as a double-voter you can just immediately be processed as a felon.
Google photo search has that capability now.
We will never see it used to prevent illegal and dead rats from voting.
I am listening to the Jeff Kuhner show, he is revealing that 4 million dead people are still on the voting lists. One voter died in 1944!
The Democrats want all those dead people on the voting list they want to keep voting crooked. The Republicans do not want to seriously challenge the Democrats probably because the Democrats are such nasty alley fighters and because the top Republicans have to make deals with the Democrats.
